Extract from STI description:

"EJ20 Boxer engine, cogged timing belt which was adapted with strengthened rubber. In difficult morosport use, this specification was used to avoid tooth jumping and to resist higher temperatures. We have been using this on the WRC car since."

As with ALL of our products, this is a GENUINE STI PRODUCT which we buy direct from Japan.

The HP600 and HP666 range of HEL Performance Brake Pads have been tested and proven in a range of competitive MSA championships and racing series in the United Kingdom and Europe.

With an impressive operating temperature window of up to 800°C, these pads will handle the most serious braking conditions and are developed exclusively for racing or track day use.

Both our brake pads give great consistency, longevity and friction at both hot and cold temperatures.

HP666

The HP666 has a ceramic kevlar compound that has a great initial bite, excellent control and pedal feel. It delivers a powerful friction coefficient of 0.42–0.57μ over a temperature range of 0-800°C. This pad sacrifices a little brake noise and rotor dust to deliver the ultimate in stopping power. This is the brake pad to choose when milliseconds make the difference between you winning and losing.

HP600

The HP600 also has a ceramic supermetal compound that has a milder initial bite than the HP666, but still retaining the same excellent control and pedal feel with a powerful friction coefficient of 0.35–0.48μ over a temperature range of 0-600°C. This is a great all-round track day pad that will outperform a lot of more expensive pads.

Eliminating Brake Fade

When brake pads run at high temperatures, a layer of gas can sometimes be created between the pad and brake disc. This can make the driver feel like they have lost braking power as the brake pedal feels the same but the car will not stop as quickly, this is called brake fade. To remedy this, a slot is cut into all HEL Performance pads to offer the gasses a route to escape.

Bedding In

HEL Performance brake pads are put through a heat curing treatment in the manufacturing process. This process removes unwanted gasses from the materials in advance, reducing the gasses that can cause fade within the brake pad. Because of this treatment, our brake pads only need light bedding in to match the padding to the disc.

Brake pads should be bedded in until up to mid range working temperature then allowed to cool properly. This will also help to removes any gasses that are still within the pad. Not following this process may cause problems leading to a decrease in optimum performance.
